    (54) Transmission operating apparatus


    (57) When a shift lever (1) of an automatic transmission is shifted to the parking position, a detent pin (6) provided on the shift lever (1) is engaged with a movable body (16) and is moved to a first position so as to be engaged with detent means (4, 7) so that the shift to another shift position is prevented. A lock means (23) is engaged with the movable body (16) which has been moved, together with the detent pin (6), to the first position so that the lock means cannot be separated from the movable body if a driver does not perform a special operation such as operating the brake. Therefore, the movable body (16) cannot be moved to the second position, and the shift lever (1) cannot be moved to another shift position. The movable body (16) is positioned at the second position when the shift lever is positioned at another shift position, and the body (16) is engaged with the detent pin (6) immediately after the shift lever is operated to the parking position (P).
